With an existing installation of Mathematica 6.0.2 under Windows, I just 
installed Player Pro.  The result: if I start Mathematica itself and 
open a new notebook there, I am prohibited from typing any and all input.

This sort of thing is intolerable!  An utterly time-frittering aggravation.

I suspect that the scenario involved here was not tested by WRI:  My 
mathpass for Mathematica itself is in the Licensing subdirectory of my 
USERBASE directory, which is the same as my BASE directory (both set by 
Windows environment variables MATHEMATICA_BASE and MATHEMATICA_USERBASE).

This is hardly the first time I have run into trouble with multiple 
passwords from multiple Wolfram Research products.  It is something they 
have just not yet gotten right.  Beware!

What I did as a temporary fix was to use my Windows backup program to 
restore my pre-existing mathpass file.  Now regular Mathematica works. 
But of course Player Pro does not.
